Honestly I feel like adding social sharing features and randomization sort of misses the point of the art piece (or at least what I got out of it). The takeaways I got were: literally anyone can create or arrange beautiful music, music doesn't have to be made by traditional means or a process, music doesn't have to be predetermined, and improvisation can be a part of any stage of the creation process. The actual soundscape a user creates is entirely secondary to the experimentation they do to get there. With no instruction besides 'play these in literally whatever way you want,' I think those additional features might change the focus to 'randomization as a musical tool' and 'how can I create the coolest soundscape?" If I was linked to the project via someone else's premade composition I would have had an entirely different experiment.
